How Can I modify the fill command?

Is there another MATLAB command like fill. If I utilize this command the output is not what I'm looking for. I want the area inside these coordinates value.

 fill(coord_x, coord_y, 'r')

The code connects the points not in the way I want. Is there any other command?

What is the way you want?

Answer 1

[Azzi Abdelmalek]

Maybe your coordinates are not correct. Look at this example

fill([0 1 1 0 0],[0 0 1 1 0],'r')
xlim([-2 2])

[Francesco]

My coordinates are theese one:

>> coord_estratte_x

coord_estratte_x =

   32.5000
   32.5000
   37.0000
   37.5000

>> coord_estratte_y

coord_estratte_y =

   17.5000
   13.7500
   16.0000
   15.0000

But I want the area inside these coordinates. It connets the points not in the correct way.

[Francesco]

The code does not know the order in which they must connect the points because it doesn't Know the area inside I want. I Know the order, the code no!

[Azzi Abdelmalek]

What is the correct way? we can't guess

[Azzi Abdelmalek]

Maybe you need to change your coordinates like

coord_x =[ 32.5000 32.5000 37.0000 37.5000]
coord_y =[17.5000 13.7500 15.0000 16.0000]
fill(coord_x, coord_y, 'r')

[Francesco]

Yes It's good. I have just thought something like this but it's not general code. In this case it's ok, but I have to do a general code: this is the problem. The area command is like fill and the code do the same thing. Is there any other command?

Try patch().

[Francesco]

Azzi, I voted your questions because you are fine and polite. The questions is:

1) If I have some points How can I color the area enclosed by the outer segments?

[Francesco]

Image the patch command do the same! :

Francesco, thanks for your remarks, but accepting an answer means your problem is solved, you can vote an answer, but don't accept it until it helps you,

Try this

coord_x =[ 32.5000 32.5000 37.0000 37.5000]
coord_y =[17.5000 13.7500 16.0000 15.0000]
[idx,idx]=sort(coord_y)
fill(coord_x(idx), coord_y(idx), 'r')

Find the centroid of the points. Then sort all of the points according to their polar angle relative to the centroid. If you sortrows() of the angle and the radius and then you reverse the order then it will be counter-clockwise and largest radius first, which happens to be one of the better ways of creating polygons.
